There is an issue with current SSH client implementation.
Given a single host public key in the known_hosts file,
host ssh-ed25519 key...
Calling ssh.Dial(`tcp`, "host", ...) will return an error
knownhosts: key mismatch
from [handshakeTransport.enterKeyExchange], because only key
"mlkem768x25519-sha256" is checked on the client side.
This changes add DB interface for knownhosts that have two methods:
- HostKeyAlgorithms: return the host key that matches in known_hosts
based on the "host" name or address for
[ssh.ClientConfig.HostKeyAlgorithms].
- HostKeyCallback: return the ssh.HostKeyCallback for
[ssh.ClientConfig.HostKeyCallback].
